Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I compiled both VLC and Mplayer with alsa support, but none of those two work well with alsa When I try to use gmplayer with alsa it gives me the following error

Code:

alsa-control: mixer attach /dev/mixer error: no such file or directory

I do get sound but the popup window with the error keeps coming up so I can't really watch a movie. I checked and /dev/mixer does exist (it's a symlink to /dev/sound/mixer). With VLC I don't get any error, not even in the shell. The program plays any file, but I just don't get any sound when using alsa. Both programs work with OSS (but I prefer to use alsa). It's not a permissions problem as the rootaccount has the same problem and all other programs work well with alsa. How can I solve this small problem?

Yes I have Both Cedega and Crossover also do not work with alsa. I found some info on this and apparently wine has some problems with the dmix plugin (which I use) in recent alsa versions. I tested it and I think the same problem occurs with VLC, 'cause I do get sound through alsa when I disable the dmix plugin. So for those programs I will just have to wait for an update But then there is still the error I get with MPlayer Could somebody help me on this one?

I have the same problem. There is something wrong with gmplayer (GUI of mplayer) in MPlayer 1.0pre5. I guess this is the verison you are using.
There are few ways to bypass the problem::
* use ESD as an audio driver in gmplayer
* use mplayer from command line
* use kplayer or kmplayer (KDE GUIs for mplayer)
